Abstract

Soils are subjected to dynamic loading of various forms. Some of these result from sources such as earthquakes, traffic loads and tidal action. To assess the level of the consequent ground motion of the soil, two parameters those are vital in dynamic analysis; shear modulus (G) and damping ratio (D) properties (Adnan et. al, 2007, Adnan and Wijeyesekera, 2008). Dynamic properties of soils such as sand, silt and clay have been studied for more time in the past (Chen et al., 2007, Hyde and Ward, 1985). However only a insignificant amount of work has been done on the dynamic properties of peat. This paper presents experimental results based on the undrained cyclic tests on different peats. Samples were collected from Holme Fen Post, Cambridgeshire and Solway Post, Carlisle. VJTech Cyclic Triaxial Testing Apparatus was used to measure these parameters. The significance of peat type, microstructure, loading frequency, confining pressure and index properties are also discussed.
